Description
Technical field
This utility model relates to a kind of quick-opening device for gas filter.
Background technology
China's natural gas is popularized utilization rate at civilian aspect and is got more and more, and gas filter is in use
Maintaining seem more and more important, existing filter uses flange and enters with flange cover bolt
Row is fastenedly connected, and such gas filter maintaining difficulty in use is relatively big, dismantles, assembles
Blind flange is highly difficult.
Gas filter is during conveying gas uses, owing to the impurity in gas is to filter element filtering
Impact, needs cleaning or changes filter element, thus needing to dismantle blind flange, owing to bolt exists
Routine work is likely to occur corrosion condition, thus can take the longest in the work of demounting bolt
Time, after clearing up simultaneously or changing filter element, assembly flange bolt of cover setting is wasted time and energy and is taken for a long time
(it is generally required to about 2 hours or longer time).Due to during fastening bolt fastening method unreasonable,
Firmly the most unbalanced there will be gas leak phenomenon, thus can re-start dismounting and assembly flange lid fastens again
Bolt.Maintenance time is longer, affects the properly functioning of fuel gas transmission, causes to the gas for domestic use of the people
Difficulty.
Utility model content
In view of this, this utility model provides a kind of gas filter quick-opening device, when changing filter element
Realize Fast Installation, dismounting.
For solving above technical problem, the technical solution of the utility model is: a kind of gas filter is fast
Opening apparatus, including the pedestal for being connected with gas pipeline, is provided with for blocking pipe in described pedestal
The blind plate in road, described blind plate is provided above the snap ring for fixing blind plate；Described snap ring is arranged on and sets
It is placed in the draw-in groove on base internal wall；Also include the lifting device for lifting blind plate.
Improve as one, between described blind plate and pedestal, be provided with O-ring seals.O-ring seals
By crimp, fill up the gap between blind plate and pedestal, it is to avoid the safety that gas leakage brings is hidden
Suffer from.
Improve as one, the inwall that described pedestal is adjacent with blind plate has mounting groove, described O shape
Sealing ring is placed in mounting groove.
Improving as one, described lifting device includes that screw rod, described screw rod lower end are fixed with blind plate；
Also including the thread bush being placed on screw rod and being provided with the female thread coordinated with screw rod, described thread bush leads to
Cross pivoted arm to be connected with pedestal.More saved for lifting blind plate by the screw rod cooperated and thread bush
Power, and can stagnate in any position, it is to avoid blind plate falls.Make more to pacify when changing filter element
Entirely.
Improving as one, described pivoted arm upper end is fixed with thread bush, and its lower end is connected with pedestal and can
Rotation.By rotating pivoted arm so that blind plate can move in the horizontal direction, thus departs from pedestal scope,
Avoid hindering the replacing of filter element.
Improve as one, described screw rod is provided with the handwheel driving screw rod to rotate.Driven by handwheel
Dynamic screw rod rotates convenient, laborsaving.
Improving as one, be provided with ring-shaped step in described pedestal, described blind plate is installed on step.
It is easy to location.
Of the present utility model have the beneficial effect that the gas filter quick-opening device with said structure,
Solve filter dismounting, assembly work difficulty when maintaining to blind flange, be greatly saved
Maintenance time and maintenance man-hours cost, improve production efficiency.Use quick-opening device dismounting, dress
During adapted the shortest, through repetition test, dismounting, installation time just can complete in 5 minutes.It is only
Special self-locking type seals structure, due to internal positive pressure, when equipment is lower eternal in working order
Cannot open.After equipment pressure release, before movable blind plate lid opens, quick-opening device filter container
Intrinsic pressure all released after, snap ring could be taken out, when have a surplus pressure time snap ring forever cannot take out beat
Open, it is to avoid the potential safety hazard brought due to maloperation.For the filter being relatively large in diameter, dismounting,
Assembling is the most convenient.The manufacturing cost of quick-opening device and the method using same type grade simultaneously
The expenses such as orchid, blind flange, connecting bolt, nut are almost equal.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Labelling in figure: 1 pedestal, 2 O-ring seals, 3 snap rings, 4 blind plates, 5 screw rods, 6 thread bush,
7 handwheels, 8 pivoted arms.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model, knot below
The utility model is described in further detail to close detailed description of the invention.
As it is shown in figure 1, this utility model includes the pedestal 1 for being connected, described base with gas pipeline
In seat 1, the blind plate 4 for blocking pipeline is installed, concrete, it is provided with ring-shaped step in pedestal 1,
Described blind plate 4 is installed on step.Described blind plate 4 is provided above the snap ring for fixing blind plate 4
3；Described snap ring 3 is arranged in the draw-in groove being arranged on pedestal 1 inwall；Also include for lifting blind
The lifting device of plate 4.Described lifting device includes screw rod 5, and described screw rod 5 lower end is solid with blind plate 4
Fixed；Also include the thread bush 6 being placed on screw rod 5 and being provided with the female thread coordinated with screw rod 5, institute
State thread bush 6 to be connected with pedestal 1 by pivoted arm 8.Described pivoted arm 8 upper end is fixed with thread bush 6,
Its lower end is connected with pedestal 1 and can rotation.The handwheel 7 driving screw rod 5 to rotate it is provided with on screw rod 5.
